Intumescent & Smoke Seal Replacement in Hatfield

Whether it is a block of flats, a school or a care home in Hatfield, our fire door seal replacements follow the same door-by-door method and report format.

Intumescent seals are strips set into the edge of a fire door or its frame that expand when heated to close the gap around the door. Smoke seals, usually brush or fin seals, block cold smoke before the intumescent reacts. Both are part of the door's tested performance.

Intumescent & Smoke Seal Replacement in Hatfield: questions

Can intumescent strips be painted?

Brush and fin smoke seals should never be painted, because paint stops them working. Some intumescent strips tolerate a light coat, but the safest rule is to mask all seals before decorating and replace any that have been painted.

Do you cover the area around Hatfield?

Yes. As well as Hatfield itself we cover nearby towns including Welwyn Garden City, St Albans and Potters Bar.

Does regulation 10 apply to buildings in Hatfield?

Yes, if the building is a multi-occupied residential building with storeys over 11 metres. Hatfield is in England, so the quarterly communal door checks and annual flat entrance door checks apply to those buildings.

Will new seals fix a door with big gaps?

No. Seals only work within the gap they were tested with. Gaps outside tolerance need the door adjusting first.
